I Tn (2Z1 echoinit may concern Be it known that I, EUGENE GRUENE- WALD. citizen of the United States, residing at Moline, in the county of Rock Islandand State of Illinois. have invented certain new useful Improvements in Automobiles,

of which the following is a specification, reference being had therein to the accompany ng drawlng.

This invention relates'to improvements in motor supports.

It is particularly adapted for use in connection with motors mounted upon a framework which is submitted to twisting and bending strains such as are incurred in motor car structures.- a

Figure 1 is aplan view of an automobile frame with a motor mounted thereon. Fig. 2 is a front elevhtion in detail showing the suspension of the front end of themotor. Fig.3 is a fragmentary vertical longhtudinal section on the line 3-3 of Fig. 2.

Fig. at is-a sideelevation of a motor withparts broken away. Fig. 5 is an end elen the drawings5 the:nume'ral 1 indicates the rectangular frame such as is common in all motor vehicles. siliently mounted upon. ground wheels 2. They frame 1 comprises the two longitudinal parallel bars or channels'3, 3 joined at the rear end by the'channel 4 and atthe front .endby a cross bar'5'. H v 4 v p The motor indicated in general by the numeralfi is shown in the drawings at of thefouncylinder internal combustion type and is supported at its front end upon the center of the transverse piece 5 and at its 7 rear end upon a cross piece 7. The motor is formed about the upper half of it's" crank case ii, the oil well or lower half' of the the crank case 9 being detachably secured to the iower edges of the case 8 and thecylinders ,10 bolted to the upper portion of the case 8. any wheelll is mounted upon the rear end of 'a crank shaft 12' and is connected through a clutch mechanism 13 to a shaft" 14 whichentends rearward to a transmission which, as it forms no part of; the present inrention is not shown in the drawings. 5 extend outwardand nearward from rank case to the transverse bar 7 to which-they aresecure'd; This :formsatwo point support for the reai'ofthe motor This framework is re- A forward extending lug 16 is cast integral with the casing Sabovethe crankshaft.

'The head is placed upon the lug 16 with its curved. surface downward. An S-shaped bracl'ret 19 has its upper portion shaped to fit within the channel 5 and its lower portion formed in a socket 20 within which rests the hemisphericalhead 17. The upper end of the bracket is secured to the channel 5 by means of rivets 21.

The motor resting at its forward point ,upon the hemispherical head 17 forms a universal connection with the frame through the, medium of the socket 20 and the bracket 19. A clevis 22 extendsover the top of the front end of the lug 16 and downward over the sides of the bracket 19. Across, the lower ends ofthe clevis is placed a bar 23 which supports a heavy coilspring 24 positioned between it and the lower face ofthe. bracket 19.; The lower ends of the clevis are threaded and nuts 25 hold the.

bar 23-up against thespring. Two wings 26 extend outward from the edges of the bracket 19 so as to further strengthen the structure. A lug 27 formed upon the upper surface of the bar 23, together with a depression 28'on the lower face of the bracket 19, hold'the'springssecurely in place and prevent-their displacement. With this arrangement of parts the front end of the motor issupported at a single point by a universal connection. The connection is by means of. a half ball and socket which permits of all wear being easily taken up by. means of the spring 2- Where this connection is made'by means of a ball and socket of'the ordinary type, the joint soon shows'wear and as'the wear cannot be'taken np,'results in a'pounding and ineflicient connection. The connection is a flexible one and the amount of friction between the parts may be varied by' varying the'tension upon the coil spring. The positioning of this"semi-ball-andesocket between the motor the framerat the" forward end of the motbrwith.thei mounting of the rear end of "the notonat twoflpointsupon a transverse.

bar, forms a suspension which allows the fIfllTlQfgtO be warped or twisted without throwing the shaft out of alinement. By

using a clevis straddling the upper part of I the four ground wheels, the main frame the connection, the necessity of drilling a hole vertically through the ball and socket for the reception of a bolt is eliminated. In this way themaximum bearing surface be.- tween the two parts is obtained and the parts are not weakened by the removal of metal from their centers. In the type of connection'in which the semi-ball-and-socket are secured together by a bolt passing di rectly through the parts, it is evident that any relative movement not in a plane perpendicular to the axis of the bolt will cause a binding or even bend the bolt in such a manner as tomateriallyinjure the connection. In my connection these difiiculties are eliminated and the ease and rapidity with which the parts may be assembled is greatly increased.
